Love Live! Sunshine!!

Otonokizaka High School stands on the border of three cities: Akihabara—a pop culture mecca that's evolving by the minute; Kanda—a conservative, cultured city where history and tradition reign supreme; and Jinbo—a quiet area reserved for a more mature, sophisticated population. Amidst this culture clash, the school now faces closure due to the enrollment of fewer and fewer students. With the school planning to close within three years, nine female students come together with one thing in mind—form a pop idol group to revive the school's popularity and keep it from shutting down. "In order to protect our beloved school, there's only one thing we can do... become pop stars!" Their goal is simple: Become an overnight sensation and use their nationwide media exposure to promote their school and bring in a wave of new students to the ailing area. A simple but solid plan, they figure. Naturally, they're nervous and wonder if this plan can really succeed, but for better or worse their new journey has begun... "All we can ask for is just a tiny bit of support from you. We truly believe that with your help, we can change the world around us. We will make our dreams come true!"

Tokyo’s brand-new Yuigaoka Girls’ High School has no history, no upperclassmen, and no reputation—its first students are starting from scratch! A team of five girls led by Kanon Shibuya discover school idols, and their hopes to do something with singing begin to grow. They begin the “School Idol Project” with a blank slate and infinite potential. It’s time for their Love Live to take flight!

In the film's story, Uranohoshi Girls' High School's idol group Aqours has won the final Love Live! contest. While preparing to enroll at a new school, the first- and second-year students encounter unexpected trouble. Also, after heading for a graduation trip, the third-year students go missing. As they are separated, the Aqours members appreciate the weight of their togetherness for the first time. In order to move forward, they must decide how to react to their new situations.

After failing in the preliminary tournament of the previous Love Live, the members of Aqours have rededicated themselves to succeeding both as idols and as saviors of their school, making sure their home will never be taken away. But Mari learns some terrible news about their upcoming school open house event and it seems like all of their efforts will be for naught. Chika and her friends must find some way to preserve their school and carry on as idols. Either way, it looks like they'll need a miracle to get through this, fortunately, from µ's to Aqours, miracles are what idols do best.
